I am making synchronous hot ends...Not independent....So software is no issue.
So if ExtrudrBoard can be used with RAMPS I can have two additional hot ends. As I have no heated bed..three default on RAMPS and two extra will make 5 possible. Thanks to all!

Or use the Azteeg that has built in support for 5 extruders and heaters.

You can't "paint" multiple materials into the same print.

if all you want is dif colors, then yes. but why would you want 4-16  dif materials mixed?

I have seen 3D printers designed to use what can only be described as 4 Krakens in one printer for a total of 16 different filaments but the build area is small last I saw it. and I too see no practical use/need for such. its kina like the modified Pulling Tractors adding lots of engines instead of just using 1 bigger one "because they can" lol I guess.

There is no free or pay software that is not proprietary to a multi head system that one could currently use open source.

Here is a list of slicers that support 4 or more extruders:
Slic3r (open source)
Cura (open source)
KISSlicer (paid version)

To my knowledge right now the only software that supports two is Simplify3d. There is no free or pay software that is not proprietary to a multi head system that one could currently use open source.

On the subject of RAMPS, as it is without adding additional boards or circuits it can only support 2 extruders as it only has the out puts for two extruder heaters, one bed heater, three thermistor inputs, and 5 motor drivers.

I am electronics newbie....Can you please tell me in detail how exactly can I create a circuit for extra hot end using extra ramps ports.

You could do even more if you added FETs and a few resistors to the aux ports.

Can the bed heating ports also be used for a cartridge+thermistor pair?
